What do you have to click on in order to establish your Internet connection? The AT&T communication manager or something else?
It could just be a limitation of their service - the Yahoo! browser is probably just a re-branded version of Internet Explorer - which should be able to resume an interrupted download, even if it's an older version.
Also there may be an ISP or cooperative that provides wireless Internet via WiMaxx or other similar services. There are sites like this one: http://www.dslreports.com/search2/ that can help you see if there might be alternatives for you.
Years ago York came out with a natural gas powered compressor that they called the "Triathilon". They didn't last long on the market since no one ever bothered to properly maintain the engine (Most homeowners wont call for any kind of service until the A/C breaks). It would be interesting to see if someone brings the technology back.
If you look at their service intervals, it's 3, 6, 9 and 11 years. And I must admit, as I was reading through the service manual the thought of changing oil on my heat pump was a little amusing
They are in the US. My upstairs unit is making a fuss. If there is a company authorized to install in my area and if the cost is not completely outrageous (like triple replacing a traditional electric unit) I may just roll the dice. I also like that I can replace both my 4 ton units with this, and I would be gaining a heat pump for my downstairs unit and greatly improved efficiency for my upstairs unit (from recycling the engine heat).
Fascinating - it appears Southwest Gas in Las Vegas (where I grew up, ironically) in collaboration with Oak Ridge Labs are working on a smaller, higher efficiency absorption based unit - cool! Hehe - pardon the pun...
